          6.60.1. Installation of Kbd
        </h2>
        <p>
          The behaviour of the Backspace and Delete keys is not consistent
          across the keymaps in the Kbd package. The following patch fixes
          this issue for i386 keymaps:
        </p>
        <pre class="userinput">
<kbd class="command">patch -Np1 -i ../kbd-2.0.4-backspace-1.patch</kbd>
</pre>
        <p>
          After patching, the Backspace key generates the character with code
          127, and the Delete key generates a well-known escape sequence.
        </p>
        <p>
          Remove the redundant <span class=
          "command"><strong>resizecons</strong></span> program (it requires
          the defunct svgalib to provide the video mode files - for normal
          use <span class="command"><strong>setfont</strong></span> sizes the
          console appropriately) together with its manpage.
        </p>
        <pre class="userinput">
<kbd class="command">sed -i 's/\(RESIZECONS_PROGS=\)yes/\1no/g' configure
sed -i 's/resizecons.8 //' docs/man/man8/Makefile.in</kbd>
</pre>
        <p>
          Prepare Kbd for compilation:
        </p>
        <pre class="userinput">
<kbd class=
"command">PKG_CONFIG_PATH=/tools/lib/pkgconfig ./configure --prefix=/usr --disable-vlock</kbd>
</pre>
        <div class="variablelist">
          <p class="title">
            <strong>The meaning of the configure options:</strong>
          </p>
          <dl class="variablelist">

            <dd>
              <p>
                This option prevents the vlock utility from being built, as
                it requires the PAM library, which isn't available in the
                chroot environment.

            Note
          </h3>
          <p>
            For some languages (e.g., Belarusian) the Kbd package doesn't
            provide a useful keymap where the stock <span class=
            "quote">&ldquo;<span class="quote">by</span>&rdquo;</span> keymap
            assumes the ISO-8859-5 encoding, and the CP1251 keymap is
            normally used. Users of such languages have to download working
            keymaps separately.
